Standard Interfaces

Abstract

A number of interface standards have been developed for computing systems. Many of these standards are useful for embedded computing. We review the organization of the Open Systems Interconnection (OSI) and then describe several useful embedded system interface standards, including I2C, USB, WiFi, Zigbee, Bluetooth, and BLE. We discuss the implications of Internet-enabled embedded devices that make use of standard interfaces.
